7229 working face of Xutuan coal mine of Huaibei Mining Group is the working face with large cut-ting height,the mining height is up to 6.3m.In order to find out the mineral pressure regularity , the systemat-ic mine pressure observation system was carried out , it is not only give effective guidance to safety production of the working face, but also has important practical significance for the safe and efficient exploitation of future working face with large cutting height in Xutuan coal mine.
